■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to
recirculated air mode automati-
cally.
This may also reduce fuel con-
sumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by selecting
the outside/recirculated air mode
switch.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning the cooling and
dehumidification function on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn the cooling and dehu-
midification function off, the win-
dows may fog up more easily.
●The windows may fog up if the
recirculated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up
by the vehicle is still drawn into the
vehicle after closing the windows, it
is recommended that the air intake
mode be set to outside air mode and
the fan speed to a ny setting except
off.
■Outside/recirculated air mode
●Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is selected.
■Operation of the air condition-
ing system in Eco drive mode
●In Eco drive mode, the air condi-
tioning system is controlled as fol-
lows to prioritize fuel efficiency:
• Fuel cell system and compressor
operation controlled to restrict
heating/cooling capacity
• Fan speed restri cted when auto-
matic mode is selected

washed, drive slow ly and apply the
brakes several times to dry the
parts.
■Bumpers

repellent coating
●The following precautions can
extend the effectiveness of the
water-repellent coating.
• Remove any dirt, etc. from the front side windows regularly.
• Do not allow dirt and dust to accu-
mulate on the windows for a long
period.
Clean the windows with a soft,
damp cloth as soon as possible.
• Do not use wax or glass cleaners that contain abrasives when
cleaning the windows.
• Do not use any metallic objects to remove condensation build up.
●When the water-repellent perfor-
mance has become insufficient,
the coating can be repaired. Con-
tact your Toyota dealer.
■Plated portions
If dirt cannot be removed, clean the
parts as follows:
●Use a soft cloth dampened with an
approximately 5% solution of neu-
tral detergent and water to clean
the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
■Roof film (vehicles with elec-
tronic sunshade)
●Dirt like bird droppings and oil
should be cleaned off with a neu-
tral detergent immediately.
●When something was attached on
the film and its mark remains. The
small mark can be recovered by
dryer heating.
●Do not apply any films on the film.
●Do not use wax that contains
abrasives.
●In case of the film repair, please
request at your Toyota dealer.
